Hi, Dcanp. I'm in the same situation and we have decided to move forward with Yardley. I guess it all really depends on where you're coming from and what you want. We wanted a larger home with more property in a more peaceful setting and the Yardley area was better than anything else we saw in NJ, CT, or NY. We're currently living in NYC so it will be a huge adjustment for us both in commuting time and cost. I tried it out last week and it's a good hour and forty-five minutes to 2 hours door-to-door each way but the majority is on NJ Transit. If your'e disciplined, you can get work done to or from the city and it gives you time to decompress. But as Railman said below, it's not inexpensive. If your company has transit checks or allows you to take it pre-tax, it will definitely help. We weighed all of the pros and cons and the pros won out.
Sorry for the long response - hope that helps.
